(Phys.org)—A team of researchers working at Australia's Parkes Observatory has found the source of at least one kind of peryton—a type of radio signal similar to Fast Radio Bursts (FRBs) which are known to come from somewhere ...

NASA's Jet Propulsion Laboratory recently announced that it is developing a small drone helicopter to scout the way for future Mars rovers. Why would Mars rovers need such a robotic guide? The answer is that driving on Mars ...

When you don't know how to get to an unfamiliar place, you probably rely on a smart phone or other device with a Global Positioning System (GPS) module for guidance. You may not realize that, especially at high latitudes ...

A newly discovered planet has been observed with the Allen Telescope Array in a search for radio signals that would betray technically sophisticated inhabitants, but no transmissions have been detected.

(Phys.org) —You may know opals as fiery gemstones, but something special called OPALS is floating above us in space. On the International Space Station, the Optical Payload for Lasercomm Science (OPALS) is demonstrating ...

Many coastal areas and harbors go almost unprotected against acts of terror. Soon a new sensor system relying on signal echoes from cell towers can quickly detect even the smallest of attack boats. This mobile radio passive ...

No one knows exactly why a NASA solar probe stopped talking to Earth six weeks ago, but it's possible the spacecraft is out of power and is drifting without a way of calling for help, the agency said in an update.

Launched by the Soviet Union in 1957, Sputnik 1 became the world's first artificial satellite – a "simple" battery-powered radio transmitter inside an aluminium shell about the size of a beach ball. This started a race ...
